Best way to clean liner

[InTheSwim1969]

Hi Everyone,

Was swimming yesterday and I noticed some brownish spots on my liner between the top of the water and the rails inside the pool. Tested immediately after noticing and all levels are perfect.

What is the best way to clean and what exactly are those spots?

Thanks All and Happy Summer!

I use test strips, nothing complicated. Not looking for a chemical analysis here, i just want to know what those spots are and the best way to clean them.

Thanks.

Don't come in here telling us your "levels are perfect" and then come back with that line when asked for numbers. Not providing test results from a real test kit is a great way to get zero help from us.

The spots could be anything from rust behind the liner to tree sap to algae to gooey sunscreen residue.

If they're above the waterline, try a Mr Clean Magic eraser on them.

I get this and at first thought it was because i had some tanning oil on when i went in but now I'm thinking it's more because of the pine tree that is close by and keeps dropping little orangish pieces into it. I personally mixed some cheap dish soap (low lather), bleach and Resolve upholstery spot cleaner and it works wonders. I spray it around the water rim when I get in, let sit a few minutes and lightly scrub with a soft bristle scrub brush. Kills the no-seeums that were biting me too. Hopefully I'm not hurting my liner but I don't think so.
